BOX.

SPECIFICATION forming part of Letters Patent No. 732,156, dated June 30, 1903.

Application filed August 4. 1902. Serial No. I 181290. -'No model) a paper box for containing a plaster-of-paris bandage.

The primary object of the invention is to provide a moisture-proof box which shall be light in weight, inexpensive to manufacture, and simple in construction.

The invention has other objects in view, which will appear hereinafter in the detailed description, reference being had to the accompanying drawings, in which- Figure 1 illustrates the complete box with the cover removed. Fig. 2 shows the manner in which the moisture-proof covering is applied to the bottom of the inner shell. Fig. 3 is a sectional view of the box with the cover thereon. u

Like numerals of reference designate corresponding parts in the several figures, and referring thereto 9 designates the body, which comprises the inner shell 10, the outer shell 11, and the bottom 12, and 13 is the cover of a box embodying my invention.

In the drawings I have illustrated a round box in which the bottom consists of a circular disk held in the lower end of the body by a strip of paper 14., affixed with paste to the meeting edges of the body and bottom, as shown in Fig. 3, or by other suitable means. The cover likewise consists of a disk 15, secured within the annular rim 16 by means of a strip of paper 17, affixed with paste to the meeting edges of the rim and disk. I do not limit myself, however, to this manner of constructing the bottom and cover of the box, as it will be apparent that other constructions may be availed of in connection with my invention with equally satisfactory results.

The inner shell is open at top and bottom and is arranged to rest on the bottom of the box and extend above the outer shell 11, preferably to the top of the cover, as shown in Fig. 3. The bottom of the inner shell is inclosed and protected by a paraffined covshells.

ering 18, which when the box is completed rests on the bottom of the box and is held tightly in place between the inner and outer This paraffined covering for the lower end of the shell may be conveniently applied by arranging the covering in the form of a disk, Fig. 2, on the upper end of the outer shell before the inner shell is inserted therein and then pressing the inner shell into place against the disk, whereby the disk will be 'drawn tight across the end of the inner shell coverings at the ends of the inner shell thus provide a complete and moisture-proof seal at each end of the shell and effectually protect the contents of the box. It is customary to apply paste to the end edges of the strip of which the inner shell is made,and I have found that a box constructed in accordance with my invention with each end of the inner shell sealed, as described, will keep the contents of the box in a dry condition even if the box is immersed in water. I may, however, apply a coating of paraffin on the inside of the shell.

The coverings 18 and 19 mayconsist of very thin paper disks of a suitable size, and Iprefer to dip each disk in hotliquid paraffin immediately before it is applied to the box, so that when clamped in place between the shell and the body or cover it will adhere tightly to the shell and form an effective closure and a hermetic seal.

In the particular embodiment of the invention illustrated in Fig. 3 paper disks 21 are pasted to the bottom and cover of the box, and the cover is sealed on the box by means of an inclosing paper strip 22, which entirely surrounds the box and extends from the top to the bottom thereof. For convenience in opening the box I may arrange a cord 23 between the lower edge of therim of the cover and the upper edge of the body, one end of the cord being free and adapted to be pulled to break the seal afforded by the inclosiug strip 22.

Abox embodying myinvention can be made inexpensively and very light in Weight, and the construction is such that moisture is effectually prevented from entering the box and affecting the plaster. The seal afiorded by the paraffin-paper covering at each end of the shell will not deteriorate, but will hermetically seal the shell for an indefinite period, thus preserving the contents of the box in a fresh and proper condition at all times. While the box may be employed for containing a variet-yof different things, it Will be found particularly useful for holding plaster-of-paris bandages, which must be kept perfectly dry and which are very quick to absorb moisture.

It is of course apparent that the box may be made of other material than paper, and the seal-coverings may also be made of other material, and I reserve the right to make all changes in the form and construction of parts as will fairly fall within the spirit and scope of the invention. 7

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. A paper box comprising an outer shell having a bottom, an inner shell open at both ends, a separate moisture-proof cup-like covering affixed to the inner shell over each end thereof, and a cover fitting on one end of the inner shell and over the covering thereon.

2. A paper boX comprising an inner and an outer shell, a bottom for the outer shell, a seal at each end of the inner shell consisting of a paraftined disk covering the end of the inner shell and having its edges pressed over and affixed to the side of said shell, and a cover fitting over the upper end of the inner shell and theseal thereon.

3. A paper box comprising an outer shell having a bottom, an inner shell open at each end and arranged within the outer shell with its lower end resting upon the bottom and its upper end projecting above the outer shell, a paraffined covering over the lower end of the inner shell and having its edges clamped tightly between the inner and outer shells, a paraffined covering over the uppertend of the inner shell, and a cover for the box adapted to fit tightly on the upper end of the inner shell and against the upper edge of the outer shell and clamp the covering between said cover and inner shell.
